I use fogging oil in my bikes, but I do not spray in the intake. For a two-stroke outboard, it is important to do this because the oil in the fuel lubricates the lower end. When they are not running, this diluted oil runs off the bearings and corrosion can set in. A four-stroke engine like the Spyder is less critical. Turning over the engine will spread the oil over the entire cyclinder. An outboard has an exposed flywheel, for the Spyder you could use the starter briefly.
I use an alternate method, which has worked well for my storing 20+ bikes each winter. I run down to the gas station and fill the tank, after adding the appropriate amount of fuel stabilizer. This does two things, fills the tank completely to reduce condensation, and gets the engine hot. Immediately on my return, I pull the plugs and spray in a couple of good squirts of fogging oil. Usually it will form a vapor in the hot cylinder, coating everything. You might see this vapor come out of the plug hole. Then put the plugs back in and do not turn over the engine. I feel turning it over can expose fresh metal, and cause the rings to scrape some of the fogging oil off the cylinder walls. In the Spring, I clean the plugs if necessary, and start the beasts. They will show oil smoke for a while.
